Christian Doppler


Christian Doppler was a very ambitious and fragile man, at one point in his career he taught Mathematics at the Technical Secondary middle school in Prague. He did not enjoy this kind of teaching career and was not satisfied and was determined to position his career life in a higher standing. Christian Dopplers health was never very good and sometimes he even had to take a leave of absence from his work. Alot of people under minded Dopplers math skills even though he taught mathematics he was always a little short at the top most level of mathematical research but was still a genious in his own way. He brought many ideas to the world like the doppler affect and The theory of Bradley.

Insights and influences


some influential incidences. Why Christian Doppler moved to Vienna was 1."France established a second republic, central europe was going through liberal

political reform, revolts lead to failure and depression. The european revolutions of 1848 were a series of political upheavals throughout the european continent. Although most of the revolutions were put down violence was everywhere, with hundreds and thousands of people tortured or murdered." I think that this would be a great reason to leave to Vienna because he probably didn't want to be around all the deppressive occurences and violence that was spreading through the country.

Major contributions


Christain Doppler published over fifty articles on astronomy, mathematics, and physics. Dopplers research in prague was interrupted by the political incidents that happened in 1848, Which later led him to decide to flea to Vienna. There he became appointed to the head of the institute for experimental physics. Franz Unger and Christian Doppler, at thier time at the University of Vienna, were big influences on Gregor Mendel who became known as the founding father of genetics because of the training of agricultural experimentation he developed at the University of Vienna which further led to helping him experiment with garden peas and further more helped him theoretically discover that an offsprings traits from two parents is dependant on the dominant and recessive genes provided by the two parents disproving that the traits of an offspring would be a blend of the parental traits. Doppler also tried to apply the Doppler affect to light waves although he had little imapct on success his thoeries influenced another. Armand Fizeau in 1848 suggested that at high relative velocities the apparent color of the source would be changed by the motion or in other words an object moving toward the viewer would appear bluer an object moving away would appear redder. Thus the doppler shift is created. The Doppler shift is used to measure the rate of recession or approach relative to the earth.

Things They Left Behind


The doppler effect discovered by christian doppler has been helpful in creating, using, and understanding many devices of technology today. Like for instance medical technicians apply it in there work by monoriting blood movement or with ultra-sounds. Doppler radar is used by police officers when they are monitoring the speed of your car when they want to check for speeding violations. Meteorologists also use doppler radar to help them perdict weather patterns or even storms.2. "By detecting the direction and velocity of raindrops or hail, for instance, Doppler radar can be used to determine the motion of winds and, thus, to predict weather patterns that will follow in the next minutes or hours. But Doppler radar can do more than simply detect a storm in progress: Doppler technology also aids meteorologists by interpreting wind direction, as an indicator of coming storms." The doppler effect wasn't only applied to soundwaves however he also applied it to light waves in 1901. The doppler effect demonstrated by light can be shown by using a spectroscope, which measures the spectral lines of an object of known chemical composition.
